Mr. Morris is threatened by Spy Smasher with death because he was called to Washington D.C. to organize U.S. radio for its part in the defense program. Billy decides to call on Captain Marvel to act as bodyguard but in disguise. Although Morris averts danger, Marvel learns that Spy Smasher has stolen the army's newest and most secret weapon: a gas so deadly that there is no defense against it.

Indexer Notes

Part 4 of the Captain Marvel vs. Spy Smasher storyline, which continues in the Spy Smasher story in this issue.

The splash page figure of Captain Marvel is also found on the cover of Whiz Comics #16.

Beck sometimes drew Pete Costanza into the Captain Marvel stories (which Costanza then inked), as in this one where he appears as an un-named salesman. Information verified by P. C. Hamerlinck in Alter Ego #126 (July 2014) and added by Craig Delich.

Spy Smasher uses his Hypno-Ray Flashlight on a group of common laborers to put them under his spell, then uses the men to cause havoc and destruction. When the former hero begins using a cyclone machine of some kind, Captain Marvel vows to stop him.
